Trying to Block a small group of pages using an iRule

You're were quite close. Try the code below.

 

Cause:

 

Your

[HTTP::uri]

function had unnecessary appendix

 

 

Mere recommendations:

 

the

[HTTP::path]

function will suffice here

 

-glob

flag in the switch statement is not required since you dont have any specific expressions such as wildcard symbols

 

when HTTP_REQUEST {

  switch [string tolower [HTTP::path]] {
    "/apscript.html" -
    "/appdet.html" {
      drop
    } default {
      return 
    }
  }

}
